Check out slides.com If you want to skip the heavy lifting and/or use a presentation platform based on reveal.js.
Everything is still easy to customize. The platform provides a UI to work from and an easy way to share your stuff.
BTW - I have no affiliation with slides.com, or even a current account. I used the service a few years back when I regularly presented and wanted to get over PowerPoint, Google Slides, Prezi, etc.
